@K11M1 nothing for this?

not ban, just a warn maybe. also, i am not an admin, so i can only report. it is not my responsibility to warn or ban. if you really want a list —————————————————- Rule 1 - angry "If you guys can help me then reply me orelse please stay away" rule 2 rule 3 - "Exam" rule 7 - did all this just after joining rule 14 rule 1 implied i assume (admin discretion needed) - passive agressive, desperate "If you are a intellegent come on i will give a problem solve it then i will accept you" "@Tazmikar heyy please msg me personally" "Heyy msg me sister" also, reporting me for no reason?

How can we concotatnte in c

How can we concotatnte in c

+ operator with strings

U can google it u know... instead of typing that here

No you cant. You cant add 2 char* pointers

Hey fam. Still putting my head around array bounds checking If y'all don't mind what are its disadvantages?

Bounds checking requires the compiler to add extra information to your executable. This could be information like storing the length of the array along with the array during both stack and heap allocations. Also code needs to be added to check the bounds are not exceeded during each array access. Sometimes this is not straightforward with pointers coming into picture which just adds adds more gruesome runtime checks to the mix. If bounds are exceeded then either an exception must be thrown (an expensive operation by itself) or the program must be aborted. All of these impose significant run time impact and were considered not acceptable for a systems programming language when C and C++ were designed. So it is left to the programmers instead. Having said that, Rust shows us a way to design a system programming language which does bounds checking with very low cost runtime overhead with its fat pointers. But Rust does this because of the way it was designed. Unlike C++, it wasnt designed to be a better C but instead it evolved a new programming paradigm itself. C and C++ unfortunately cant do the same.

#include <stdio.h> void swap(int* xp, int* yp) { if (xp == yp) // Check if the two addresses are same return; *xp = *xp + *yp; printf("%d xp",xp); *yp = *xp - *yp; printf("%d yp",yp); *xp = *xp - *yp; } int main() { int x = 10; swap(&x, &x); printf("After swap(&x, &x): x = %d", x); return 0; } Can anyone tell why this """printf("%d xp",*xp); printf("%d yp",*yp);""" doesn't print anything???

Because you are returning when xp == yp. Is it so hard to figure this yourself from your code? And your code for swapping will invoke Undefined Behavior if the addition results in an overflow.

It's a little bit confusing

xp is initialized with &x and yp is also initialized with &x. So xp==yp is true. If this is the case you run the statement return which just returns from the function. Code following that will not execute. I expected more from a Peaky Blinder.

😄 well said aunt Polly

Hi

Can someone tell me more about this program?

Hi

#Puzzle #include <iostream> using namespace std; class Test{ public: Test() try : c{nullptr} { //constructor body throw 0; } catch(...){ cout<<"Exception"; } private: char* c; }; int main(){ Test obj; } Why does this code throw an exception in main when the exception has already been caught earlier and the code is not explicitly rethrowing the exception?

Hi, can anyone teach me python/java/html? pls for my studies. Sorry if it's something not related to the group.

Google it!

I have presentation about robotic. I need references for components in Robots and list of languages use in Robotic. Please help me and recommend references

#include <stdio.h> int main() { // Write C code here int a=0,b=1,n,temp; printf("Enter the number of fibonacci series to be generated"); scanf("%d",n); printf("The fibonacci series is :"); printf("%d%d" , a ,b); for(int i=2 ; i<n;i++){ temp = a + b; printf("%d" , temp); a=b; b=temp; } return 0; }

#include <iostream> int main() { std::cout<<5.00975542f<<"\n"; std::cout<<5.00975542; return 0; } Both outputs only 6 significant number. But double has more precision right?

#include <iostream> int main() { std::cout<<5.00975542f<<"\n"; std::cout<<5.00975542; return 0; } Both outputs only 6 significant number. But double has more precision right?

but, as we have used pointer, then the address is saved of the variable x

Precision doesnt mean the number of digits displayed. Precision defines that the maximum difference between a floating point representation of a number and the actual number wont be greater than 10^-6 for floats and 10^-10 for doubles. For float the precision is at minimum 6 and for double the precision is at the minimum 10. Expressed as a percentage it is 10^-4% for float and 10^-8% for double.

Double has more precision but you will not able to show until you use fixed setprecision(decimal points value)

Here in this code.... isn't ptr variable's scope is limited to function only....and isn't memory containing 'x' variable will be deleted once fun() get returned(or pop from stack).....how

but when precision increases the significant figures on the decimal side also increases right ?

int* fun() { int x = 20; int* ptr = &x; return ptr; } // Driver Code int main() { int* arr = fun(); cout << *arr; return 0; }

we can try by manipulating the pointer data also, it will result in changed value of X

int* fun() { int x = 20; int* ptr = &x; return ptr; } // Driver Code int main() { int* arr = fun(); cout << *arr; return 0; }
